Please update to the stable release 3.2.1.

With 3.2 you have "debug_options 11,2" which will produce a full trace
of HTTP headers in cache.log which will greatly help understanding why
the 502 occured. (careful about size and confidential info if this is
used on a production machine)

I also suggest using the squid format for access.log, it includes
details such as the IP of the server which that 502 is related to.
